I don’t think you will find any disagreement on either point.

“Democracy” is often used as a general term for governments that in some sense are a delegation of citizen power. Even though a pure democracy would remove the delegation.

As a practical matter, the US model has devolved into a party-duocracy. Power at all levels has nearly completely centralized at the national level of each majority party. Of which there are only two. The extreme minimum of choice even for a Republic.
